Biology     Glossary (e.g. epibenthic)

Length based on occurrence record; to be replaced with better reference. Common on exposed sand flats and close to dead coral areas. Shallow subtidal zones. Feed on sea urchins of the "sand dollar" group. Egg capsules forming an irregular mass which is the result of several females spawning together (Ref. 349). Members of the order Neotaenioglossa are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults (Ref. 833).
